Investigation of Electroencephalogram (EEG) has been made during the spontaneous breathing and paced breathing control (9 breaths/minute) conditions in eight young healthy college students (Male=4, Female=4). Their selected 5-minute EEG segments were transformed into 3 frequency bands (Delta Wave: 0.5–4Hz, Theta Wave: 4–8Hz and Alpha Wave: 8–13Hz). The power in each band were compared between two...
Fetal Movement (FM) is a marker for evaluating wellbeing of the unborn baby. Naturally, pregnant women can sense any movement in her abdomen. However, there are two groups of women who may have degraded this sensing ability. A primigravida, a first time pregnant woman, may not be able to recognize the fetus movement. A working pregnant woman may be too busy to aware of her fetus responses. In this...
Two types of augmented feedback (FB) were compared during reaching training in the Virtual Reality (VR) environment for chronic stroke patients. Six participants were assigned to receive either the Knowledge of Result (KR) or the Knowledge of Performance (KP) FB. They went through 12 training sessions, of which there were 75 Reach-to-Target trials in the VR. They were instructed to perform the actions...
Foot deformity is a common problem among Thai people. It is resulted from various causes. The deformity may lead to pain and discomfort of feet and legs. The foot condition can be evaluated using plantar pressures and foot deformity measures, depending on the therapists. This paper presents a design of digital podoscope, a screening tool for patients with foot deformity. Built on a commercial optical...
Respiratory is known to be a confounding factor of Heart Rate Variability (HRV) analysis. This article introduces a Breath-to-Breath Interval (BBI) spectral computation to investigate the insight between respiration and the HRV. Six males and five female volunteers (age 20–25 years) underwent the Electrocardiogram (ECG) and respiratory chest movement recordings for 5 minutes while sitting in resting...
A modular design of Electrocardiogram (ECG) acquisition system is presented. As a crucial part of the system, the Front-End module is made of a programmable, mixed-signal Application Specific Integrated Circuit (ASIC). This module is designed to satisfy the various forms of bioelectrical measurement with no hardware modification. Controlled by a 32-bit microcontroller, the prototype module recorded...
This article explains the signal processing of the Heart Rate Variability (HRV) data analysis on both temporal and spectral domains. Downloaded information of 35 Ventricular Tachycardia (VT) records, the Electrocardiogram (ECG) was step by step converted into autonomic quantitative measures. The overall process included R-wave detection, R-R interval (RRI) construction and time-to-frequency domain...
Number of people who is suffering with plantar is increasing nowadays. Several causes such as diabetes mellitus, plantar fasciitis, changes in biomechanics, etc. may be diagnosed. Simple treatment, by an expert clinician, is such as inserting a custom-made insole into the patient's shoes for manipulating pressure to the right position. This work aims to develop plantar point pressure measurement,...
